CAUTION
Improper operation of a hoist can create a potentially hazardous situation which, if not
avoided, could result in minor or moderate injury, or property damage. To avoid such a
potentially hazardous situation THE OPERATOR SHALL:
• Maintain a firm footing or be otherwise secured when operating
the hoist.
• Check brake function by tensioning the hoist prior to each lift
operation.
• Use hook latches. Latches are to retain slings, chains, etc. under
slack conditions only.
• Make sure the hook latches are closed and not supporting any
parts of the load.
• Make sure the load is free to move and will clear all obstructions.
• Avoid swinging the load or hook.
• Make sure hook travel is in the same direction as shown on
controls.
• Inspect the hoist regularly, replace damaged or worn parts, and
keep appropriate records of maintenance.
• Use the hoist manufacturer’s recommended parts when repairing
the unit.
• Lubricate load chain per hoist manufacturer’s recommendations.
• NOT allow your attention to be diverted from operating the hoist.
• NOT allow the hoist to be subjected to sharp contact with other
hoists, structures, or objects through misuse.
• NOT adjust or repair the hoist unless qualified to
perform such adjustments or repairs.

3.0 Operation
3.1 Introduction
3.1.1 WARNING HOIST OPERATORS SHALL BE REQUIRED TO READ THE OPERATION SECTION OF THIS MANUAL, THE
WARNINGS CONTAINED IN THIS MANUAL, INSTRUCTION AND WARNING LABELS ON THE HOIST OR LIFTING
SYSTEM, AND THE OPERATION SECTIONS OF ANSI/ASME B30.21 and ANSI/ASME B30.10.
3.1.2 Measure and record the “k” dimension of the top and bottom hook. See Table 4-3 under Section 4, “Inspection”.
3.1.3 WARNING For the LX1A model hoist, lifting a light load (approx. 11 lbs. or less) may not produce full braking performance
and slippage can occur.
3.2 Free Chaining
3.2.1 DANGER
„ Do not operate the hoist in free chain mode while a load is applied to the hoist.
„ Set the select lever to the lifting (‘UP’) position before performing a lifting operation. Do not leave the lever in the neutral
(‘N’)
position.
„ Do not pull the no-load-side chain with the select lever set in the lowering (‘DN’) position. This will cause the lever to rotate,
which can be hazardous.
3.2.2 Free Chain Principle
„ Free chaining allows the load chain to be moved freely because the brake is released under no load situations.
„ An internal spring releases the mechanical brake allowing the load chain to be pulled in either direction to the desired
length.
„ The brake is engaged during lowering or lifting the load.
